'SOLE-LEVELING- MACHINE.

Specification of Letters Patent. Patented s l -1 7 i Application filed February 18, 1915.. Serial No. 7,985.

To all whom it may concern: 1

Be it known that I, l/VILLIAM C. ,B x'rnn, a citizen of the United States, residing at rleverly, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Sole-Leveling Machines; and I do hereby declare the fol lowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to sole leveling machines of that type in which the leveling of the sole is effected by a vibrating leveling'roll which is caused to travel along the sole and to change its relative lateral inclinationby relative movement of the roll carrier and jack on which the shoe is supported.

In operating upon certain classes of work the leveling of the sole may be facilitated, and a better finish given to the, sole, if the sole is subjected to heat as well as pressure during the leveling, and it is the object of the present invention to provide novel and improved means by which this result may be secured in a reliable and satisfactory manner in leveling machines of the type re-.

ferred to. To this end the invention contemplates the provision of means for heating the leveling roll or rolls during the the leveling operation. In the preferred form of the invention the leveling roll is mounted on'a hollow shaft secured in the vibrating roll carrier, and provided with radial holes forming gas jets to which gas is supplied through suitable piping connected withthe end of the shaft. With this construction the roll may be readily and economically heated to the desired temperature without interfering with the proper operation of the roll upon the sole.

The invention will I from 'an inspection of the accompanying drawings and the following detailed de scription of the mechanism illustrated therein.

In the drawings, Figure 1 is a side elevation showing an automatic leveling machine embodying the invention in its preferred form; Fig. 2 is a detail side elevation showing the roll carrier and the devices for heating the roll; and Fig. 3 is ascetio nal plan view of theparts shown in Fig. 2.

In the drawings the invention: is illusbe readily understood trated asembodied' in an automatic leveling machine having substantially the construction and mode of operation of the machine shown and described in Patent N 0. 1,011,801,

December 12, 1911', and Patent 0. 555,548,

March 3, 1896. 'Ihis machine comprises gen orally, two shoe supportingj -acks, two vibrating leveling rolls cooperating respectively therewith, mechanism for actuatingtlie acks tochange the relative longitudinal.position of the acks and rolls, means for connecting and. d sconnecting each jack .andfthe jack i WILLIAM G.

CURPC'RATIGN, OF EATERsO NEW JERsfiElip oscillating mechanism, an d means for-tip ping the rollsto change the relativelateral inclination of a jack. and 'itscooperatingroll during, the leveling operation. In Fig. 1 the vj acks 2 are shown mechanism of the patents above referred to.

The leveling rolls 6 are mounted tolvibrate in the position which they assume when disconnected from the jack oscillating mechanism. -'The jacks are pivotally mounted at 4 in the front in roll carriers 8 secured to sleeves 10 mount f ed to turn in roll'carrying beds -.12whieh' are pivotally mounted at 14 in the upper The. r 5 1 eration toehangethe lateral inclinations-of the rolls by mechanism which is fully derear portion of the machine frame. sleeves 10 are rocked during the'levellng opscribed in the "patents above referred to.

Each roll 6 is mounted to turn freely upon a shaft 16, theends of whichare mounted in the arms 18 of a yoke, the rear end-of the roll carrying sleeve lOand'is rapidly reciprocated to vibrate the leveling roll byan I which is connected to thefront end of'a' rod f 20. The rod20passes through the center of eccentricsecuredto the constantly rotating;

shaft 22. The fo rward ends of the-yoke arms 18 are guided in ways 24 formed in 1 I the side bars vofthe' roll carrier 8, and serve to support and guide the yoke and leveling roll as the yoke and roll arefvibrated.

In embodying the invention in a leveling machine'having'the construction'above described, the shaft 16 isprovided with. a central bore 26 and with radial holes 28 which are arranged Within the roll 6 and form gas jets through which gas may be supplied to the bore. The means for supplying gas to the hollow shaft 16 comprises roll carrier. union 34 with a supply'pipe 36 which extends along the side of the roll carrier and is "supported by a bearing 38 through which 7 surface of the Tell. It alsoenables the teinr it slides freely during the oscillation of the leveling roll- The free end of the pipe 36 is connected by a fieXible'tubelO with a gas supply pipe 42 which may be provided with a valve 44: for regulating the flow of gas to the gas jets within the leveling roll. The flexible connection between the pipe 36 and pipe 4-2 allows the roll carrier 8 to rise and fall and to tilt laterally without interfering fwiththe supplypf gas to the'jets Within the leveling roll. y I

r The above construction provides a simple and efiicient means for heating the leveling roll'duringthe leveling operation without interfering with the'movements of the roll requisite for 1)ropei'ly leveling the sole, and without danger of'soiling the sole engaging perature to be readily regulated'in accordance with the character of the work being done and in such manner as to secure the best results. Y a 5 r T v Havingexplained the nature and object of the invention; and specifically described one form of mechanism in which it may be embodied, what is clained is 2- A sole leveling machine comprising a roll carrier having a slotted side bar, a yoke slidingly supported in the carrier Ineansfor vibrating the yoke within the carrier, a nonvrotatable hollow shaft-mounted in the yoke and having aseries of fuel passages coinrnun'icating with the central bore, a fuel pipe connected tothe end of the shaft and passing through the slot in the side bar and an open ended hollow leveling roll journaled upon the shaft and heated by jets of lame within the roll and issuing from the fuel passages in the shaft, the products of coinbustion passing out through the open end of the roll.
